Description: Materials relating to Radin's study of the Wappo language. Consists of four notebooks, titled "Wappo linguistics [IV, V, VI, and VII-VIII]," containing text in Wappo and, in at least one case, some interlinear translation. Notebook IV contains a brief section of conjugations, 180-183; and genealogy, 184-185. Radin's note, 1947, indicates that part of the material was published. See also Radin (1929a).
